Title: Suspension device for vehicles running upon rails
IPC: B61F5/10
Filed: 1933-05-09
Abstract: 412,745. Railway - vehicle undercarriages; dashpots. MESSIER, Y. L., 179, Boulevard Brune, Paris. May 9, 1933, No. 13479. Convention date, May 10, 1932. [Classes 103 (vi) and 108 (iii).] Relative lateral movement between the axles of a railway vehicle and the vehicle or bogie frame is cushioned by arranging therebetween an aperiodic damping device, such as a liquid dashpot comprising an apertured and spring- controlled piston connected to one of the parts and movable in a cylinder connected to the other part, provision being also made for permitting the necessary relative vertical movement. In the construction shown in Fig. 1, the axle E is rotatable in a casing F on which is fixed a piston P having apertures o allowing the transfer of liquid, the piston being returned to its central position by springs R. A vertical guiding of the cylinder C, which permits the axle E to assume an inclination to the horizontal, is effected by providing it with trunnions t pivoted centrally in blocks p slidable in vertical guides g rigidly connected with the vehicle frame L. In a modification of this construction (Fig. 2, not shown), the axle E is arranged parallel to a transverse shaft passing through the cylinder C, being connected to the shaft by parallel longitudinal arms. In a somewhat similar construction, Fig. 4, the parallel arms are replaced by leaf springs B<1>,by the flexing of which the axle ends may assume different levels. In further constructions the leaf springs are replaced by rigid arms and the necessary flexibility is furnished either by the torsion of the shaft T itself, or by arranging centralizing springs between the rigid arms and the tines of a forked block secured to the shaft T. Suitable bearing means for interposition between the axle casing F and the body to permit the lateral movement of the axle comprises two pneumatic or oleo-pneumatic cylinders C', C<2>, Fig. 9, in which slide pistons P<1>, P<2>, the rods T<1>, T<2> of which are slidably mounted by plates Z<1>, Z<2> on the axle casing. A pipe Y connects the compression chambers so as to equalize the pressures therein. Dashpots, construction of.-In order to dispense with the necessity of making the axle F or shaft T a fluid-tight fit in the cylinder C, the latter may be fitted with a central partition D, Fig. 10, having liquid transfer orifices e, while on the shaft T are mounted two pistons K<1>, K<2> having narrow upper passages n<3>, n<2> controlled by valves c<3>, c<2>, and wider lower passages n<4>, n<1> controlled by valves c', c<1>. The outer chambers a<1>, a<2> contain control springs r<1>, r<2> and serve for return of leakage fluid to the system, and are preferably connected at their upper and lower parts by pipes y<b>, ya to equalise the levels of oil in the chambers. Specification 280,547, [Class 108 (iii)], is referred to.

Title: Improvements in or relating to the manufacture of electric fuzeheads such as are used, for example, in blasting detonators
IPC: F42B3/198
Filed: 1937-05-18
Abstract: 495,833. Electric fuzeheads. CAMPBELL, B., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. May 18, 1937, No. 13906. [Class 9 (i)] A process for the manufacture of low-tension electric fuzeheads, as used for example in blasting - detonators, comprises the step of cutting, rebating or otherwise forming a step near the extremity of an element consisting of a single thickness of insulating-material coated on each surface with an electrically conducting layer or film of metal. As shown in Figs. 3 and 4, a blank consisting of a single sheet of pressboard 11 having metal foil coatings 12, 13 is subjected to a stamping operation so as to produce two identical combs 9, 10, each consisting of a number of connected triangular teeth as shown in dotted lines in Fig. 3. Each comb is then passed through a rebating-machine so as to cut a step in the extremity of each tooth and the comb is then passed under a high speed brush in order to remove any fibres or fine metal particles. Fig. 5 is an end section through one of the teeth of a single comb after completion of the operation and showing the step 14. A bridge wire and a bead of ignitable composition are then applied to the step in known manner. A coating of metal foil may be applied over only a part of the one surface of the blank so that the area where the step is to be formed is left uncovered. Alternatively, the metal foil may be applied over the whole of both surfaces of the blank so that in the subsequent rebating operation the appropriate section of the foil is cut away as well as part of the insulating-material beneath. In forming the step, it may, however, be sufficient merely to remove the metal layer or film. The coatings 12, 13 are preferably of brass foil which is secured to the pressboard by means of a thermoplastic cement, e.g. as described in Specification 495,832.

Abstract: 877,926. Slitting tyre treads. FIRESTONE TIRE & RUBBER CO. April 21, 1960, No. 14031/60. Class 31 (1). [Also in Group XXII] Apparatus for slitting a tyre tread as the tyre is continuously rotated about its axis comprises an expansible inflatable chuck A, Fig. 2, for mounting an inflatable tyre B, reciprocable slitting assemblies D, said slitting assemblies comprising knives which are pivotable to permit travel with the tyre tread when it is pierced, and drive means operable to rotate the chuck and simultaneously to reciprocate the assemblies D. Lubricating assemblies C continuously supply water or other liquid to the tyre tread to lubricate the slitting knives. The drive means comprise a motor-driven shaft 101 which through gearing drives a ring gear 119 supporting the chuck A and has connected thereto connecting rods 120, 121 pivotally connected to slides 122, 123 supported by slideways 126, 127 respectively. Each slitting assembly comprises a knife head 210, Figs. 8 and 9, secured to a bracket 203 pivotable about a pin 204 against the action of a spring 215. The knife head supports a bracket 208 from which protrude slitting knives 231, 232 and 233. The knife head is adjustable vertically by means of a hand wheel 237 and the knives are adjustable horizontally by means of set screws 234, 235 and 236. The knife head can be extended or retracted by means of an air cylinder 244, Fig. 2. In operation, a tyre is centred on chuck A and the chuck expanded to seal the tyre beads while the tyre is inflated. The shaft 101 is driven to drive the ring gear 119 to rotate the tyre and simultaneously to reciprocate the slides 122, 123 so that the knives pierce the tyre tread. The knives turn with the tyre tread, each knife head 210 and bracket 203 pivoting around pin 204 against the action of spring 215. Subsequently, as the knives are withdrawn from the tyre, each spring 215 returns bracket 203 to its initial position. Upon completion of the slitting operation, shaft 101 is stopped, chuck A collapsed and the tyre deflated for removal from the chuck. To facilitate such removal, each air cylinder 244 is actuated to retract slitting head 210 from the tyre.
